A former security advisor of Germany says the six-party nuclear talks will serve a key role in the future unification of South and North Korea.

Horst Teltschik, who had led German unification along with former Chancellor Helmut Kohl, pointed out that the United States and then Soviet Union played important roles in the unification of Germany in 1990.

He went on to say that inter-Korean unification would be difficult without cooperation from Japan, China and Russia and the United States.

He said that Seoul needs Washington’s support to ensure security in the unification process, noting that a unified Germany would have been impossible without the help of the United States.

Teltschik also noted that in the 1980s, West Germany provided 200 billion marks to East Germany and prepared for gradual unification. At the time, there was both support and criticism from the West, but in the end, East Germany collapsed and the two were unified. He stressed the importance of continued support and expanded exchange.
